STORMPROOF UMBRELLA.

Application filed July 14,

The main object of this invention is to provide an umbrella which automatically folds into closed position when subjected to a too strong wind pressure. This invention aims to provide an umbrella which does not turn inside out in a wind, but on the contrary folds ina common manner, thereby reducing the projected pressure surface to a minimum. V-

The above and other objects will become apparent in the description below,'in which characters of reference refer to like-named parts in the drawing.

Referring briefly to the drawing, Figure 1 is a longitudinal sectional elevational view of the storm-proof umbrella, showing the same in partly closedposition.

Figure 2 is a view similar to Figure 1, showing the umbrella in opened position.

Figure 3 is an enlarged sectional elevational View of the tubular stafi', showing the means of locking the reciprocating rod in one of two positions.

Referring in detail to the drawing, the numeral 10 indicates a rigid tubular memher which serves as a staff and at its lower end has a stud 1 f integral therewith, which latter is embedded in a handle 15. Within the hollow chamber 13 of the staff near the upper and lower ends, a pair of resilient curved fingers 11 and 12 are mounted. These fingers are curved inwardly into the chamber 13 of the staff and cooperate with a rod 16 for locking the latter in either extended or retracted position. The rod 16 fits loosely in the hollow staff 10 and near its lower end is provided with an annular recess 16 which is engaged by the curved portion of the resilient fingers 11 or 12, according to which position the rod 16 finds itself in. At the upper end of the rod 16 an annular flange is located. To this rod radiation ribs 18 are pivotally attached. These ribs have the usual shed omitted for the sake of clar- Intermediatethe length of these ribs, lugs are formed and to these lugs support ribs 19 are pivotally attached. At the upper end of the hollow staff 10, a stop collar 20'is provided which limitsthe outward motion of sleeve 21 but does not interfere with the motion of rod 16. This sleeve 21 carries an encircling flange to which the support ribs 19 are piv- 1926. Serial No. 122,353.

otally attached, but does not interfere with the motion on rod 16.

The article is adapted to serve as a stormproof umbrella- Ordinarily, all these devices which lay claim to this feature turn inside out when subjected to wind pressure. In this case, as the'wind strikes the surface of the shed beneath the ribs 18. pull is exerted on the rod 16. This releases the recess from the tongue 12 and permits the rod 16 to partly slide out of the hollow staff 10. In sliding out rod 16, the ribs 18 are folded in the position shown in Figure 2 to that shown in Figure 1 thru the medium of the support ribs 19, which have one of their ends attached to the flange of the sleeve 21 while the opposite ends are pivotally at tached to the ribs 18 intermediate their length. The umbrella when folded offers no further resistance to the wind and consequently will not become disabled. hen not in use, the umbrella is folded by pushing inward rod 16 overcoming the pressure of the outer resilient fingers and sliding the sleeve 21' along with it until rod 16 and sleeve 21 are in the position near handle 15 and finger 12 has snapped into rod 16.

It is to be noted that certain changes in form and construction may be made without departing from the spirit and scope of the invention.

I claim 1. In an umbrella, a hollow staff having a handle at one end, a'cylindrioal rod slidable in said hollow staff, ribs radiating from said rod, said rod being telescoped into said staff when said ribs are extended, a resilient arcuate tongue near each end of said staff. and recesses in one end of said rod receiving said tongues for releasably securing said rod in extended or retracted position.

2. In an umbrella, a hollow staff having a handle at one end, a cylindrical rod slidable in said staff, ribs radiating from said rod, said rod telescoping into said staff, an outwardly curved arcuate resilient tongue near each end of said staff extending into the bore thereof, and a recess at the lower end of said rod receiving the curved portion of the tongues for releasably securing the rod in the extended or the telescoped position.

In testimony whereof I affix my signature.
